Kata clips: Shoto ryu Karate Jutsu with Simon Keegan
The kata Wansu (called Empi in some styles) is thought to be the first kata introduced to Okinawa. In its original form it was introduced to Ryukyu by a Chinese Hsing-I Quan boxer called Wang Ji in 1683. It was transmitted by Okinawans Hama Higa and Takahara Peichin and passed into the Tomari Te style.
The kata Kushanku (called Kanku Dai in some styles) was also one of the earliest kata introduced to Okinawa, It was introduced in around 1756 by Chatan Yara and Tode Sakugawa (student of Takahara) who had trained in China with a Wang Zong Yue who later gained fame for teaching a style of Quan Fa to the Chen family which later evolved into Yang style Taiji Quan.
The kata Passai (called Bassai Dai in some styles) was devised in Okinawa by Sokon Matsumura who had gone to China to train in Fujian in 1828. He may have trained in Bazi Quan (the forerunner of Baji Quan) which included forms called Baji Da and Baji Xiao (similar to Bassai Dai and Bassai Sho).
